The area of circle is 275 cm². What is the circumference of circle:
Answer: 58.79 cm

Given area = (275 = \pi r^2), so (r^2 = 275/\pi), (r \approx 9.36) cm. Circumference = (2\pi r \approx 2 \cdot 3.14 \cdot 9.36 \approx 58.79) cm. Studying this highlights geometric calculations, providing lessons on applying formulas for practical measurements in design and engineering.
